IMPROVEMENT IN TOY WATCHES.

Specification forming part of Letters Patent No. 195.434, datedSeptember 18, 1877; application filed September 6, 1877.

To all whom it may concern:

Be it known that I, LOUlS L. GRANDPER- BET, of New York city, county andState of New York, have invented an Improvement in Ioy Watches, of whichthe following is a specification:

The object of my invention is to so construct a toy watch that motionwill be imparted to a balance-wheel, so that it will have areciprocatory motion similar to that of the balancewheel of aregularly-constructed watch, and showing the action of the hair-springand balance-wheel through an opening in the back case of the watch, thusmaking an attractive toy.

In order to show an additional movementthat is, a movement of the hands1make my with the spur-wheel 9. his a spring, acting to raise the upperend of the lever, and also to raise the pawl h. A spur-wheel, g, isattached to the arbor of the balance-wheel, and a pin, m, passes throughthe stem in the watch, and engages with the bent leverf.

When the pin m is pushed down, the pawl k and ratchet a cause the handsto move a certain distance, and the lower end of the lever f, engagingwith the spur-wheel 9, causes the balance-wheel to revolve until itwinds up the spring 6. Then, by releasing the pin m, the force of thespring a will cause the wheel to revolve and reciprocate for some lengthof time, in the same manner and with the same apparent motion as thebalance-wheel in an ordinary watch, the balance-wheel being seen througha glazed opening in the back of the watch.

What is claimed is- The combination, in a toy watch, of the pin m,spring k, leverf, spur-wheel g, balancewheel 0, and spring 6,substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
